On your tutorial you only control one LED i'm trying to figure out how can i add 2 switches and instead of LED i'll put relay. How can i do it? can you give me some idea. Thanks in advance. :D

You would have to use a transistor as an electronic switch. However this won't work very well because the input signal is square wave, which would have the effect of repeatedly turning the switch on and off very fast.

To do what you're requesting, a new circuit would have to be built/added to modify the square wave to a on or off signal.
